Neural Regulation

39.6K
Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Amyloid Fibrils

9.7K
Amyloid fibrils are aggregates of misfolded proteins.  Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils. 
Amyloid deposits were observed as early as 1639 in the liver and the spleen.   In 1854, Rudolph Virchow performed iodine staining,...

Parkinson's Disease: Overview

625
Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is...

Summary

Alpha-synuclein (α-Syn) pathology is linked to inflammation and microbial imbalances in neurodegenerative diseases like Parkinson's. Mitigating chronic inflammation may offer a new strategy for managing these conditions.

Area of Science:

  • Neuroscience
  • Pathology
  • Immunology

Background:

  • Alpha-synuclein (α-Syn) is crucial for synaptic vesicle function.
  • α-Syn aggregation into Lewy bodies, alongside inflammation, characterizes α-synucleinopathies like Parkinson's Disease (PD).

Purpose of the Study:

  • To review α-Syn's mechanistic links to inflammation.
  • To explore the role of microbial dysbiosis in α-Syn pathology.
  • To investigate the potential of anti-inflammatory strategies for managing α-synucleinopathies.

Main Methods:

  • Literature review of mechanistic pathways.
  • Analysis of studies on microbial dysbiosis and α-Syn.
  • Exploration of anti-inflammatory interventions.

Main Results:

  • α-Syn pathology is intricately connected with inflammatory processes.
  • Microbial dysbiosis may influence α-Syn aggregation and spread.
  • Inflammation mitigation presents a potential therapeutic avenue.

Conclusions:

  • Clarifying α-synucleinopathy pathophysiology is essential.
  • Targeting low-grade chronic inflammation could aid in management and prevention.
  • Further research is needed for clinical recommendations.
